That would be an e/c/u/m/e/n/i/c/a/l/ political matter, I fancy.Not to mention semantic, since you first have to define "race" and "intelligence".As a matter of interest, has there been any quasi-religious uproar, in scientific circles, about the following recent - and related - claim?

The new study, from the University of Edinburgh, highlights the contribution of rare genetic variants which appear to have a disproportionate impact on intelligence.

Scientists examined thousands of genetic markers in the DNA of 20,000 people looking for signals associated with IQ.

They found that the combined effect of rare and common genetic variants explained at least half of the difference in intelligence between individuals.

This matched estimates from earlier twin and family studies that had been suspected to be overestimates, as previous molecular studies of the human genome concluded around 30 per cent.
